mm/slab_common.c: use list_for_each_entry in dump_unreclaimable_slab()
dump_unreclaimable_slab() acquires the slab_mutex first, and it won't
remove any slab_caches list entry when itering the slab_caches lists.
Thus we do not need list_for_each_entry_safe here, which is against
removal of list entry.
